51单片机I2C通信, 用c语言编写， 经proteus可以运行-I am not able to speak English

练习一I/O控制 练习目的:1.掌握单片机I/O口控制方法。2.掌握Keil与Proteus的使用方法。练习内容：参考例程，掌握Keil与Proteus的联调使用方法。画出电路，编写一段程序，用P1 口作为控制端口，使8个LED 轮流亮。画出电路，编写一段程序，用P1.0~P1.6 口控制LED，P1.7 控制LED 的亮和灭(P1.7 接按键，按下时LED 亮，不按时LED 灭。)-Exercise I/O control, practice the purpose of a master M

It is a complete project of a four digit clock developed with Proteus and CCS compiler. In the project I used a PIC16F628 microcontroller, 4-digit 7 segments displays, two buttons and two leds. It is possible to set the current hour and alarm.

通过Proteus模拟单片机,实现音乐盒（祝你平安）的开发 工程开发环境：Proteus7.5,Keil C51 Vision3 8.02版 开发语言：C语言 参考书：51单片机工程师是怎样炼成的——基于C语言+Proteus仿真（老杨编著）-By Proteus simulation microcontroller to achieve Music Box (I wish you peace) development project development environment:

Hello.I send you 5 AVR projects with c language . each project contains : c code , simulation in proteus and hex file . Thanks
